# Have I rearranged this formula correctly?

Hi there,

I'm studying hydraulics and hydrology this semester, I'm just a little rusty on formula manipulation and want to ensure I have does this correctly.

Any feedback would be appreciated. I want to make k the subject please see attached.

Nope
divide both sides by Lv^2 and multiply each side by 2gD giving HL x 2gD/Lv^2
N

Nope, don't think you have
(assuming you initial formula is correct) to rearrange and get k =
divide both sides by Lv^2 and multiply by 2gD to get k=HL x 2gD/Lv^2

Brilliant, thank you very much. I knew something didn't quite feel right, need to brush up on some basics!
